To all 'whom t may concern.'

Be it known that I, CHARLES E. Nonn- QUIsT, a citizen of the UnitedStates, residing at South Connellsville, in the county of Fayette andState oi Pennsylvania, have invented certain newv and usefulImprovements in an Injector, of which the following is a speciiication.

rlhe present invention relates to an injector used for the purpose ofmixing water with steam for use upon steam boilers and the like. Theprincipal object of the invention is to provide a device of this naturewhich will be simple and eiiicient in construcl= tion, reliable inoperation, durable, easily assembled and disassembled.

l/Vith the above and numerous other objects in view as will appear asthe description progresses, the invention resides in certain novelfeatures of construction, and the combination and arrangement of partsas will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a longitudinal vertical section through thedevice,

Figure 2 is a detailed perspective of the inner tube thereof,

Figure 3 is a perspective oi the nipple used in conjunction therewith,and

Figure 4 is a detail transverse section taken substantially on the line4 4 of Figure 1 looking in the direction of the arrows.

Referring to the drawing in detail it will be seen that 1 represents thetubular casing Vwhich is open at its ends and provided with a branch 2adjacent one end. A valve casing 3 is mounted on the tubular casing 1intermediate the ends thereof and at a point diametrically opposed tothe branch pipe 2. A wall 4 is internally mounted within the casing,being provided with an opening having internal threads for receiving aninner tube 5 which has a conical shaped bore 6 communicating with asecond conical shaped bore 8 which in turn communicates with a bore 9. Ashoulder 10 is arranged on the intermediate portion of the inner tube 5adjacent the threads thereof so as to abut the wall 4 and suitable lugs11 are provided adjacent thereto so that an implement may be engagedtherewith for screwing the inner tube in place. The bore 6 is incommunication with the spout 12, a slight space being allowedtherebetween for the passage of This spout 12 is mounted on the beingopen, a wall interiorly disposed in- Serial No. 584,772.

nipple 14 which is threaded in the end of the casing adjacent the branch2. It will be vunderstood that steam passes through the nipple 14 andthrough the inner tube 5 whereas the water passes through the branch 2through the space between the inner tube and the nipple so as to mixwith the steam. An overiiow valve plug is shown at 9.

A valve 15 having a stem 16 is mounted within the valve casing 3 and isadapted to normally rest upon the seat 17 and the upper Hat surface ofthe wall 4 extending across the seat 17. rlhe stem of the valve projectsthrough a bore 18 provided in the plug 19 in the opening or end of thecasing 8. Should the pressure of the water become too great this valvewill be automatically lifted thereby allowing the water to freel passthrough the casing 8 and thereby flow from one portion of the casing 1to the other portion, as is evident from an inspection of Figure 1.

It is thought that the construction and operation ot the invention willbe now thoroughly understood without a more detailed descriptionthereof, but it is desired to point out that have merely disclosed thepreferred embodiment of the invention, and that numerous changes in thedetailsof construction and in the combination and arrangement ot partsmay be resorted to without departing from the spirit of the invention ashereinafter claimed.

Having thus described m invention what I claim as new is 1. An injectoro1 the class described including a casina having a branch adjacent oneend thereof, both ends of the casing termediate the ends of the casingto divide the casing intotwo compartments, a tube extending through saidwall connecting the two compartments, said casing provided with anopening across which a portion of said wall extends, said openingconnecting the two compartments of the casing, a valve casing disposedover the opening, and a valve movable in the valve casing and seatableon said opening and the portion of said wall extended across saidopening all in the manner and for the purpose speciiied.

An injector of the class described including a casing having open ends,a branch l connected withthe casing adjacent one end, L0 a wall disposedinteriorly of the casing intermediate its ends separating said casinginto two compartments, a tube extending through said wall, a nipple inone end ot the casing adjacent the branch and extending intov one end ofthe tube, said nipple beingr vsiig'htly spaced from the end of the tube.into which it extends so that water may` pass between the nipple andthe tube from the branch, said casing'provded with an openingconnectingA the two compartments of the casing across which the wailextends,

a valve casing exterioriy of first mentioned casing over Vthe opening`and a valve thereln seatabie in the opening" and on the portion of thewaiiextended there across all in the manner and for the purposespeciied.

S. An injectorl of the class described inciuding` a casinghaving openends, a branch connected with the casing adjacent one end, a waildisposed interiorlyV of the casing intermediate its ends` separatingsaid casing into two compartments, a tube extending through said wall, anipple in one end of the kslightly spaced from the end of the tube intowhich it extends so that water may pass be-` tween the nipple and thetube from the branch, said casing provided with an o en ing connectingthe two compartments o the casing across which the Wall extends, a,valve casingl exteriorly of the first mentioned oasing over the openingand avalve `therein seatable in the opening `and on the portion of thewali extended there across al1 in the manner and for thepurposespecified, und a stem extending from the va1ve,a plug;r engagedin the Valve casing and provided with a bore for receiving the stem ofthe Valve.

In testimony whereof, 1 aix my signature in presence of two witnesses.
